Control/Operation
The electronics are centrally located in an
industry-standard switch cabinet. The machine is
controlled by a Beckhoff computer with a
Windows 10 operating system. This opens up
unlimited possibilities for automation and
expansion. Machine operation, monitoring and
settings can all be completed on a 12-inch colour
touch screen. Optionally, a tablet with a 12-inch
screen is available that is connected to the
machine via WLAN. The system can also be
connected to an external network. Remote
maintenance/access via VPN can be easily and
securely implemented over a LAN or WLAN
connection.
Drive System
The machine is driven by a 15-kW electric motor.
A tractor power generator or a diesel emergency
generator can be used when the machine is
operated in the field. The electric motor is the
most efficient power supply with just €3.00 per
hour in electricity costs. This is also a significant
advantage when the system is used in industrial
plants, where filling the bale chamber sometimes
takes longer. The baler waits during the filling
process without consuming energy
unnecessarily.
LISIBACH----------------------
Filling the Baler
The baler can be filled on the left or right side of the machine. A
dosage wagon dumps the maize directly into a receiving
hopper. The machine can also be filled from above with a
telescopic loader. For stationary operation, the system is also
available without a filling system.
Filling System
The maize is transported
directly from the feeder belt into
the bale chamber by the
vertical conveyor and linear
conveyor. The filling process
does not need to be interrupted
once the baling process has
begun. The maize is piled
above the bale chamber and
serves as the supply for the
next bale. If this storage space
is insufficient, the maize is
transported into the storage bin
via the return conveyor. The
volume of the bin can
accommodate up to 6 bales.
--------MASCHINENBAU
Storage Bin
The machine can be continuously fed
with maize. If the baler cannot process
everything, the maize is temporarily
stored in the 16 m3 hopper. If filling
process is too slow, the machine
automatically takes additional material
from the storage bin. The scraper floor
conveys the material back onto the
vertical conveyor. This allows the
machine to be fully utilized even when
less or no material is being filled.
Linear Conveyor
The linear conveyor conveys the
material into the bale chamber and, if
that is overfilled, then directly into the
storage bin. The linear conveyor can
be lowered for road travel.
Compression System
The bale chamber has two
transversely arranged rams. The
chamber is filled directly by the filling
system. No pressing energy is
consumed. The distribution rollers
ensure uniform filling of the bale
chamber. The density of the bales is
determined by the current opening of
the bale chamber. Using the control,
the operator can select the maximum
opening of the rams, and thus
determine the compression ratio, to
match the material.
LISIBACH-----------------------
To press more air out of the
material, it is compressed
beyond the bale form and
compacted. The ram then
moves back to the ejection
position to relieve the pressing
force. This results in bales with
significantly increased
dimensional stability. Wrapping
the bale with normal stretch film
allows for better absorption of
the pressing force.
When the entire volume of the open bale
chamber is filled, both rams begin to close at
the same time. All the material is compressed
in one step. The final dimension after
compression is always the same and
corresponds to the machine-specific bale
size. The time needed to compress the
material is only 10 – 14 seconds. The
maximum pressing force is 28 tons per
square meter. This results in a force of up to
35 tons per ram.
Wrapping Table – 2nd
Wrapping
The ejection cylinder pushes
the bale directly onto the
wrapping table. The table
turns the bale as the rollers
simultaneously rotate the
bale on the table. Normal
stretch film from a film roll
with a width of 750 mm is
wound around the bale. In
order to absorb the enormous
pressing force, a film
thickness of 35 µ (at least
30 µ) is recommended
instead of standard 25-µ film.
Four layers of film are applied
horizontally on the wrapping
table using this method. The
cost for these four layers of
35-µ film is approximately
€2.00.
--------MASCHINENBAU
Wrapping Ring – 1st Wrapping
Four covers open once the bale is
completely pressed together. The
covers guide the bale when it is
ejected. Normal stretch film with a
width of 500 mm is wrapped around
the open covers. In order to absorb
the enormous pressing force, a film
thickness of 35 µ (at least 30 µ) is
recommended instead of standard
25-µ film. While the wrapping ring
wraps the film around the bale, a
cylinder pushes the bale out of the
bale chamber. This combination
creates a spiral wrap over the entire
length of the bale. Four layers of film
are applied to the bale in this step.
The cost for these 4 layers of 35-µ
film is approximately €1.90 and they
replace the bale net or mantle film
usually used by other machines.
Stacking and Transporting Bales
The bales are removed from the wrapping table with a suitable feeder. For easy handling, we offer an
optimised square bale gripper. The bales can be easily stacked thanks to their square shape. Several
bales can be stacked on top of each other. Compared to round bales, square bales are easier to load
onto trailers, to secure and to transport. They also save space.
Opening the Bales
The enormous bale density is also evident when they are
opened. Since only stretch film is used – no bale net or
mantle film – it is also very easy to open the bale. Simply
clamp the bale and cut the film. Then squeeze the bale a
little more and the maize falls out. The film then lies on top of
the maize heap. Alternatively, the bale can easily be picked
up with a bale fork or a fork with grapple. If the film is cut
open, the maize falls out and the film remains on the
tips/tines. This is a great advantage when filling feed mixers.
If just a little feed is used each day, it is possible to cut a
standing or lying bale slice by slice, just like a sausage. The
rest of the bale remains tightly packed thanks to the
wrapping in two directions.

What Makes the DifferenceLittle space required to operate the machine.
Square bales for easy handling, stacking and transport.
Minimal maintenance and upkeep costs.
Process completely automated, fixed/constant cycle time per bale.
Easy to operate and maintain.
Not dependent on the manufacturer for a long period of time, thanks to the use of standard parts.
Maintenance/ServiceUse your time at home to load the machine with film, not to service it. We use 6 machines in our own
contracting company – we know what we are talking about! Low wear, minimal maintenance, no
components that require constant monitoring. If a part should wear out, we use standard parts that are
available worldwide. This allows you to repair the machine and service it without waiting for parts from the
manufacturer or calling specialists on site.
.
Support/Remote MaintenanceThanks to the latest generation of control (Beckhoff with Windows 10 operating system), all forms of remote
maintenance and remote access are possible via VPN in order to provide on-site assistance in the event of
an emergency. Should you have any problems or malfunctions, you can contact the manufacturer directly
for assistance.
